Hibiscus plant named ‘TAHI56’

ABSTRACT

A new cultivar of  Hibiscus  plant named ‘TAHI56’ that is characterized by its upright and well-branched plant habit, its flowers that are very pale purple-white in color with a red eye, its large flowers that grow up to 25 cm in diameter, and its foliage that is green and suffused with greyed purple to brown.

Botanical classification: Hibiscus×moscheutos.

Cultivar designation: ‘TAHI56’.

CROSS REFERENCE TO RELATED APPLICATIONS

This application is co-pending with U.S. Plant Patent Applications filed for 2 plants derived from the same breeding program that are entitled Hibiscus Plant Named ‘TAHI12’ (U.S. Plant patent application Ser. No. 14/757,369) and Hibiscus Plant Named ‘TAHI16’ (U.S. Plant patent application Ser. No. 14/757,377).

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Hibiscus plant botanically known as Hibiscus×moscheutos ‘TAHI56’ and will be referred to hereafter by its cultivar name, ‘TAHI56’. ‘TAHI56’ is a new cultivar of hardy hibiscus grown for use as a container and landscape plant.

The new cultivar was developed through an on-going breeding program conducted by the Inventor in Montauban, France. The new cultivar arose from a cross made in September of 2012 between Hibiscus ‘Summer Storm’ (U.S. Plant Pat. No. 20,443) as the female parent and Hibiscus×moscheutos ‘Griotte’ (not patented) as the male parent. ‘TAHI56’ was selected as a single unique plant in September of 2012 from the resulting seedlings of the above cross.

Asexual propagation of the new cultivar was first accomplished by softwood stem cuttings in Montauban, France in 2012 by the Inventor. Asexual propagation by softwood stem cuttings and tissue culture has determined that the characteristics of the new cultivar are stable and are reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and represent the characteristics of ‘TAHI56’. These attributes in combination distinguish ‘TAHI56’ as a new and distinct cultivar of Hibiscus.

-   -   1. ‘TAHI56’ exhibits an upright and well-branched plant habit.     -   2. ‘TAHI56’ exhibits flowers that are very pale purple-white in         color with a red eye.     -   3. ‘TAHI56’ exhibits large flowers that grow up to 25 cm in         diameter.     -   4. ‘TAHI56’ exhibits foliage that is green and suffused with         greyed purple to brown.

The female parent plant, ‘Summer Storm’, is similar to ‘TAHI56’ in having foliage that is dark in color. ‘Summer Storm’ differs from ‘TAHI56’ in having flowers that are pink in color. The male parent plant, ‘Griotte’, is similar to ‘TAHI56’ in having foliage that is dark in color. ‘Griotte’ differs from ‘TAHI56’ in having flowers that are cherry red in color and foliage that is less dark in color. ‘TAHI16’ can be compared to cultivars that derived from the same breeding program; ‘TAHI12’ and ‘TAHI16’. ‘TAHI12’ differs from ‘TAHI56’ in having pink flowers with more visible veins. ‘TAHI16’ differs from ‘TAHI156’ in having flowers that are deep red-pink in color.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying colored photographs illustrates the overall appearance and distinct characteristics of the new Hibiscus. The photographs were taken of a twelve month-old plant of ‘TAHI56’ as grown in a 23-cm container in an un-heated greenhouse in Boskoop, The Netherlands.

The photograph in FIG. 1 provides a side view of ‘TAHI56’ in bloom.

The photograph in FIG. 2 provides a close-up view of a flower of ‘TAHI56’.

The photograph in FIG. 3 provides a close-up view of a leaf of ‘TAHI56’.

The colors in the photographs are as close as possible with the digital photography and printing techniques utilized and the color codes in the detailed botanical description accurately describe the new Hibiscus.
